I'm now on my second set of Hankook Ventus V2 Concept 2's and they're smooth and reasonably quiet, but not as grippy as the DWS's were. They may actually last a bit longer though.
Before the Conti's I went through several sets of Kumho Ecsta AST's. They gripped well, but wore out fast and would not stay balanced. I used to have to rebalance the Kumho's every 5-10K miles. Only got around 20K from them as well.
